Carmen posted a video of her new puppy on the internet and email to people be linked. The next day, each of these two people forwarded the link to two other people. The day after that, each of these four people emailed the link to two other people that's the pattern continues, with the number of people who received the video when he represented by a linear function or an exponential function, and why?​

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
